A Reuters exclusive reveals Anthropic is considering accelerating a model release to counter OpenAI’s recently launched GPT-6 Astra, seven days after CEO Dario Amodei published a 3,800-word manifesto on September 12 arguing for a deliberate, industry-wide slowdown in frontier model development. Amodei’s essay outlined a three-part framework emphasizing embedded evaluators, democratic coordination, and global alignment. Reports suggest the competitive pressure exerted by GPT-6 Astra may be overriding these commitments. The structural driver is Anthropic’s looming IPO, with a target valuation of up to $2 trillion and a massive $65 billion raised in its May 2026 Series H round; marketing is expected to begin as early as mid-October. For investors, including potential anchor investor Nvidia, competing directly with OpenAI’s latest capabilities is likely more material than adherence to a long-term pacing strategy. By contrast, following its March 2026 funding round, which brought its capital to $122 billion, OpenAI has explicitly ruled out an IPO for 2026, with CEO Sam Altman tying the deferral to safety obligations. Anthropic appears to be navigating the transition from a private research lab to a public-market titan.
